The best thing I can suggest is to modify the extra field tpl's on the product detail pages to not display the enabled keywords field.

Take a look at skin1/modules/Extra_Fields/product.tpl

{section name=field loop=$extra_fields}
{if $extra_fields[field].active eq "Y" && $extra_fields[field].field_value}

{$extra_fields[field].field}
{$extra_fields[field].field_value}

{/if}
{/section}

If you know the index of the keywords field you can modify the {if} condition to something like this:


{if $extra_fields[field].active eq "Y" && $extra_fields[field].field_value or !$extra_fields[1].field eq "keywords"}

This would be if you had one extra field before a second field with the name "keywords" as this would bypass the active eq "Y" condition and cause the active field not to display but still be available in the feed generator.

Hope this helps.
